Which of the following can be implemented in an IP backbone network?

Winch functions docs the beater network NMS mainly provide?

Exhibit:

As shown in the figure, complex traffic classification is configured for RTA's upstream GigabitEthernet 1/0/0. The QoS is configured as follows:

A tester sends TCP packets from GE 1/1 to GE 1/2 at 40 1.2.2 IF DSCP values of packets GE receives are not 46, what are the possible causes?

Which of the following are rules for the router to check the RPF after receiving SA messages from the MSDP?

As shown in the figure, the PHP function is enabled on all routers by default and an MPLS TE tunnel RT 1-RT 2-RT 3-RT 4-RT 5 is set up between RT 1 and RT 5. See the figure for label distribution of the TE tunnel. A bypass tunnel RT 2-RT 6-RT 4 is configured on RT 2 to protect RT 3. See the figure for the label distribution of the bypass tunnel. When RT 3 is faulty, RT 2 switches traffic to the bypass tunnel. How many MPLS labels do packets on the path from RT
6 to RT 4 have? What is the value of each label?
